Thickener N,N'-Methylenebisacrylamide MBA CAS 110-26-9 Textile Printing Grade Crosslinker

In rotary screen and flatbed printing, the rheology of the print paste decides edge sharpness, colour yield and how much dye is wasted in washing off. MBA crosslinks the acrylic thickener backbone into a lightly branched, pseudoplastic network: viscosity collapses under the shear of the squeegee so the paste flows through the screen mesh, then recovers within seconds so the printed outline stays crisp on cotton, viscose and polyester blends.

Our textile printing grade is manufactured with a controlled crosslink density and a narrow particle size distribution, which is why mills see viscosity repeatability within plus or minus five percent from drum to drum. Low free monomer content keeps the print shop free of acrylic odour and helps the finished fabric meet OEKO-TEX and bluesign restricted substance requirements, a point procurement teams increasingly audit before approving a thickener supplier.

• Controlled crosslink density: paste viscosity repeatable within plus or minus 5% between batches, so recipes do not need re-cutting on every delivery
• Electrolyte and urea tolerance: stable pastes in systems containing urea, resist salts and 10% sodium alginate without thinning or phase separation
• Sharp edge definition: rapid viscosity recovery after shear produces clean outlines at 60 to 80 mesh screen counts
• Low residual acrylamide monomer: reduced operator exposure and easier compliance with OEKO-TEX and MRSL limits
• Fast wetting and dispersion: a lump free 2% dispersion is obtained in 30 minutes at 40 degrees C with normal high speed stirring
• Low dusting crystal form: clean dosing by automatic weighing systems and less material lost to the workshop floor

The product is used to build thickener systems for reactive, disperse, pigment and acid dye printing on woven and knitted fabrics, in carpet printing where paste hold-up matters, and in pigment pad dyeing where a controlled yield value prevents migration during drying. Mills also add it to sizing and finishing formulations to raise wet pick-up without increasing solids.

For a starting point, disperse 0.3 to 0.8 percent MBA on thickener solids at 45 degrees C, neutralise to pH 7 with ammonia and allow the paste to mature for two hours before adding dye. Our technical team can run a viscosity curve against your existing thickener and recommend a matching dosage before you commit to a full drum.

A batch Certificate of Analysis reports assay, moisture, pH, residual acrylamide and viscosity of a standard paste prepared under our internal method, so your laboratory can compare numbers directly. A 500 g sample from the same lot is retained for 18 months, and third party testing for OEKO-TEX or REACH SVHC can be commissioned on request.

The product carries a 12 month warranty from shipment date under recommended storage. Any batch that misses the specification on arrival is replaced or credited after joint verification, and we cover the freight for the replacement consignment.

Standard packing is 25 kg in a kraft paper sack with polyethylene inner liner, 40 sacks to a pallet, shrink wrapped and strapped. Smaller trial quantities of 1 kg and 5 kg are available in foil bags so a mill can qualify the material on a production screen before ordering a container.

Typical lead time is 5 to 8 working days for orders below one tonne, and 15 to 20 days for full container loads shipped from Shanghai. Labels, packing list and COA are issued in English, with buyer specific marks and shipping documents available on request.
